用pchart打印输出的图片

我一直在试图在我的drupal 7网站上用pchart图库创建图表。我已经正确安装和配置pchart，当我尝试通过pcahrt本身我得到一个真正的乱码输出提供了一个例子来测试它，如下图所示..用pchart打印输出的图片

这非常冗长，只是输出的一部分。

当我把

<img src="sites/all/libraries/pChart2.1.3/examples/example.basic.php" />

线我的网页上，我没有得到任何东西，只是用标题为空页。

当我在我的页面上包含example.basic.php文件时，会得到那个乱码。

下面

是我example.basic.php代码，

<?php 
    /* CAT:Misc */ 

    //I have installed libraries module. and the contents of pChart are present in /sites/all/libraries/pChart2.1.3 

    $name = "pChart2.1.3"; 
    if ($path = libraries_get_path($name)) { 
    include($path.'/class/pData.class.php'); 
    include($path.'/class/pDraw.class.php'); 
    include($path.'/class/pImage.class.php'); 
    } 

    /* Include all the classes 
    include("../class/pDraw.class.php"); 
    include("../class/pImage.class.php"); 
    include("../class/pData.class.php"); */ 

    /* Create your dataset object */ 
    $myData = new pData(); 

    /* Add data in your dataset */ 
    $myData->addPoints(array(1,3,4,3,5)); 

    /* Create a pChart object and associate your dataset */ 
    $myPicture = new pImage(700,230,$myData); 

    /* Choose a nice font */ 
    $myPicture->setFontProperties(array("FontName"=>$path.'/fonts/Forgotte.ttf',"FontSize"=>11)); 

    /* Define the boundaries of the graph area */ 
    $myPicture->setGraphArea(60,40,670,190); 

    /* Draw the scale, keep everything automatic */ 
    $myPicture->drawScale(); 

    /* Draw the scale, keep everything automatic */ 
    $myPicture->drawSplineChart(); 

    /* Render the picture (choose the best way) */ 
    $myPicture->autoOutput("pictures/example.basic.png"); 

?>

仅供参考， 我曾与渲染画面，如试验，

$myPicture->autoOutput(); 

$myPicture->Stroke(); 

$myPicture->render();

但是，所有这些给出相同的结果..！ 那我该如何让它工作..？

不知道你的问题是，似乎它输出一个PNG图像，字节为字节， 如果添加

header('Content-Description: File Transfer'); 
header('Content-Type: application/octet-stream'); 
header('Content-Disposition: attachment; filename=image.png'); 
header('Content-Transfer-Encoding: binary'); 
header('Expires: 0'); 
header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); 
header('Pragma: public');

？

当我尝试在firefox afret保存中打开图像时，它给了我以下错误..“图像”文件：// /home/akshay/Downloads/image.png“无法显示，因为它包含错误。” – akshaynhegde 2012-02-24 17:54:18

如果您在文本编辑器中打开image.png，那么您下载的png文件是否包含任何HTML代码？ – 2012-02-24 18:00:31

某种程度上，标题信息没有被正确设置以便将图像直接呈现给浏览器。

长篇故事。使用$Image->Render("test.png")代替$Image->Stroke()，使像这样在你的页面的引用：

<img src="test.png" />

您可以参考函数autoOutput（）在pImage.class.php Line.171实施。

该功能执行的操作将因Web服务器和PHP之间的接口类型而异。

因此，乱码输出是png文件的内容。如果您在页面中注释了所有其他HTML输出，您将在浏览器中看到图表的完整图像。
